Abstract
To provide a novel cyanate ester compound that can realize a cured product having low dielectric constant and dielectric loss tangent, and excellent flame retardancy and heat resistance, and moreover has relatively low viscosity, excellent solvent solubility, and also excellent handling properties, and a method for producing the cyanate ester compound, and a curable resin composition and the like using the cyanate ester compound. A phenol-modified xylene formaldehyde resin is cyanated.
